After declining for five straight weeks, gasoline prices across Massachusetts and New Hampshire blipped upward last week, according to service-station tracking by the auto club AAA.
The U.S. coast-to-coast average also increased over the seven-day span ending Wednesday. It was the second straight week in which the national average rose, auto club figures showed.
The Massachusetts average price for self-service regular gas reached $3.703 on Wednesday, a 3.5-cent increase from the prior Wednesday’s average of $3.668, AAA reported. But Wednesday’s figure was 9.2 cents lower than the Bay State average of $3.795 recorded on the same day last year.
In New Hampshire, a 2.9-cent increase pushed the average price of self-service regular to $3.650 on Wednesday, from $3.621 seven days earlier, according to AAA. But New Hampshire’s average on the same day of 2012, at $3.753 was 10.3 cents higher than Wednesday’s figure.
Nationally, Wednesday’s AAA average of $3.589 was 4.3 pennies higher than the prior week’s $3.546. One year earlier, the national average of $3.824 was 23.5 cents above Wednesday’s level.
